The 2023 Nobel Prize in Physics is awarded to Ferenc Krausz, Anne L’Huileire and Pierre Agostini for experiments that led to the development of Attosecond Pulses of Light. We’re diving deep into the basics of Attosecond Physics with a three-episode series in Hindi for Laymen.
In Episode 1 we’ll be building our basics of vision and time. How do we capture fast motion? What is the role of the shutter in cameras while capturing fast movement? How can we capture ultrafast motion with the help of light pulses? What role does laser play in generating these short pulses of light? What exactly is an attosecond? And How is the field of Attosecond Physics born? We will deal with all these questions and more in suitable detail for laymen.
Although very basic, this video might help you brush up basics of vision, perception, light and time.
In Episodes 2 and 3, we’ll begin the journey of attosecond pulses. How do we generate attosecond pulses in the lab? What is the theoretical framework behind higher harmonic generation and attosecond pulses? What are some cool and groundbreaking applications of attosecond pulses? Creating these videos was a fun ride for me. I hope you enjoy them as well. Love, Peace and Happy Learning!

वैसे, पिछले साल 2022 का फिज़िक्स नोबेल प्राइज़ भी बहुत बेहतरीन था. वो Quantum Entanglement से जुड़े काम के लिए मिला था. उसके लिए अपन ने Quantum Mechanics की एक हल्की सी प्लेलिस्ट बनाई थी. ये वीडियो ठीक लगी हो, तो वो प्लेलिस्ट देख सकते हैं. मज़ा आएगा. इसी बावत उसका लिंक अटैच कर रहा हूं.

Bhai sahab .....
आपके 1 या दो ही वीडियो होंगे, जो मैंने नहीं देखे हैं। मैं आपको कितना एडमायर करता हूं, ये मैं शब्दों में बताकर आपको बोर नहीं करना चाहता।
बस इतनी इल्तजा है कि इस भौतिकी नोबल 2023 के अन्य दोनो वीडियो 25 से पहले अपलोड करिए, प्लीज।।।

Really love the way you explained.
waiting for next two parts
एक ही बार में पूरी वीडियो डाल देनी चाहिए थी, चाहे वह वीडियो 3 घंटे की ही क्यों न होती। क्योंकि ऐसे इंट्रेस्टिंग और कॉम्प्लेक्स टॉपिक इतनी आसन भाषा भाषा में समझना बेहद रोमांचक होता है, और मन करता है कि वीडियो खत्म ही न हो।

Bhai sabar karo..time lagata hai editing main
पता नही लोग इतने अच्छे वीडियो को क्यों नहीं पसंद करते। इतना अच्छा कंटेंट कही नही मिलेगा।
इस से ये समझ आता है की ज्ञान लेने वाले बहुत कम लोग हैं और मनोरंजन वाले बहुत लोग।
अपना ध्यान रखे। ज्ञान के साथ
धन्यवाद आयुष दादा
I am so angry when I see million likes on stupid and non sense video on Facebook TikTok and other social media
